Before you can run the sample Visual Basic macro, you must add a reference to the Graph 9.0 object model. To add the reference, follow these steps:

1. On the Tools menu, point to Macros, and then click Visual Basic Editor.
2. On the Tools menu, click References.
3. In the References - VBAProject dialog box, click to select the Microsoft Graph 9.0 Object Library check box.
4. Click OK.
   
   The project now contains a reference to the Graph 9.0 object model.

Sample Visual Basic Procedure

   Sub UpdateAllGraphs()

      Dim oShape As Shape
      Dim oSlide As Slide
      Dim oGraph As Object

      ' Loop through each slide in the presentation.
      For Each oSlide In ActivePresentation.Slides

         ' Loop through all the shapes on the current slide.
         For Each oShape In oSlide.Shapes

            ' Check whether the shape is an OLE object.
            If oShape.Type = msoEmbeddedOLEObject Then

               ' Check whether the OLE object is a Graph object.
               If oShape.OLEFormat.ProgID = "MSGraph.Chart.8" Then

                  ' Found a graph; obtain object reference, and
                  ' then update.
                  Set oGraph = oShape.OLEFormat.Object
                  oGraph.Application.Update

               End If
            End If
         Next oShape
      Next oSlide

   End Sub
